Title: Improvements in or relating to devices or appliances for use in applying to surfacesglue and other viscous substances
Inventor: EASTHAM ROLAND JAMES
IPC: B05C17/00
Filed: 1953-04-23
Abstract: <PICT:0750160/III/1> <PICT:0750160/III/2> <PICT:0750160/III/3> <PICT:0750160/III/4> An applicator for glue or other viscous substances comprises a reservoir having a discharge aperture, with a valve for opening or closing the same, in its floor, and an adjustable scraper or other device to control the thickness of the applied glue layer and which works between side pieces or walls of the applicator, the distance between the walls determining the width of a line of glue deposited on a surface by the applicator.  As shown in Figs. 1 and 2 the aperture 12, formed in a well 11 of the reservoir 10, is covered by a slide valve 14 held by its stem 14a between the floor and a leaf spring 15, and the stem is connected by a link 16 to a lever 17 detachably mounted on a shaft 18 but rotatable therewith.  The outer ends of this shaft project through a narrow raised portion 10a of the reservoir 10 and are secured in the arms of a bifurcated control handle 19, acted on by a compression spring 22, which holds the valve 14 normally in its closed position. The width of the applied strip of glue is determined by the separation of the sides of the well 11.  The scraper 13 is pivoted at 13a and is adjusted by rotating it by means of a rod 13b, which extends upwardly through a slot 20 formed in the casing of the reservoir and carries resiliently mounted projections 13c which engage in serrations 20a in the slot walls. When the applicator is drawn along the surfaces to be coated, glue is released through the aperture 12 by depressing the handle 19. In a further embodiment, Figs. 4 and 7, the reservoir 30 has at one end an aperture 31 covered by a chamfered valve plate 32a which extends upwardly and over the adjacent wall of the reservoir and is normally held in the closed position by a tension spring 33, connecting a hook 32b on the valve member 32 to a set screw 34 in the wall 30a of the reservoir.  This screw also serves to hold in adjustment a scraper 35 whose lower part 35a is angled to form one marginal edge of the aperture 31, both such edges being inclined in correspondence with the valve plate.  The valve is opened by depressing the lever 36 pivoted on a rod 36a journalled in slots in the side walls of the container.  Handgrip portions may be provided in either embodiment.  The applicator may be mounted in a stationary position, and articles to be coated passed or fed beneath it either mechanically or by hand.

Oscillating containers; air, controlling circulation of; temperature, controlling.-Drying apparatus for clothing &c. comprises a receptacle for the clothing, means for passing either hot or cold air through the receptacle, means for automatically shutting off the hot air from, and admitting cold air to, the cylinder when a predetermined maximum temperature is reached, means such as electric lamps to indicate whether hot or cold air is passing through the cylinder, and an audible alarm for indicating when a predetermined minimum temperature is reached. Means may also be provided for stopping the airfan and cylinder motors when the minimum temperature is reached. As shown, the clothing &c. is charged into the perforated cylinder 9 which is located in tha enclosed drying-space 2 of the casing 1, and which is rotated alternately in opposite directions by an electric motor 10, the current through the armature of which is reversed automatically by a rotary controller. By the depression of a pivoted hand-lever 25 which is held in position by a projection 42, Fig. 3. on an arm 43 connected to the lever engaging with a spring-latch 38 secured to a rotatable shaft 39, the interconnected dampers 19, 20, 21 are actuated so as to permit the circulation by a fan 14 of a current of heated air through the screened air inlet 13, heating-chamber 5, and drying-space 2. Upon the air leaving the drying-space at the opening 11 reaching a predetermined maximum temperature a thermostat placed outside the opening and connected by a member 72 to an electric controller 73 effects the release of the electromagnetically held locking arm 49 of the latch and the lever 25 which changes the positions of the dampers so that the air inlet 13 and the hot air passage 7 in the casing are closed, while the cold air inlet 22 and the fan outlet 16 to the atmosphere are opened, thus permitting the passage through the drying space of cold air. Electric lamps 77, 78 actuated by the electric controller are provided outside the casing for indicating the passage through the drying space of cold and hot air respectively. When the cold air leaving the drying-space reaches a predetermined minimum temperature the thermostat effects through the controller 73 an electric circuit through an audible signal 81 which warns the attendant of the completion of the drying and cooling operations. The controller may, however, be adapted to stop either or both of the motors driving the cylinder and the fan.

Title: Improvements in or relating to High Speed Motion Picture Cameras.
IPC: G03B39/04
Filed: 1968-03-08
Abstract: 1,188,924. High speed cinematography; automatic speed control. RED LAKE LABORATORIES Inc. March 8, 1968 [March 15, 1967], No.11562/68. Headings G2E and G3R. In a high-speed cine camera of the continuous film feed type, film is drawn from spool 16 to a motor-driven take-up spool 18, and a de-coupling device isolates that part of the film passing through gate 21 from forces tending to change the film speed from a selected value. Mechanical de-coupling is provided by an idling toothed sprocket 28 which engages the film both approaching and leaving the gate, and by spring- loaded idle rollers 32 on mounts 29, 31. At the highest speeds, the inertia of sprocket 28 may be avoided by choosing a film path which by-passes the sprocket. Electronic de-coupling comprising a speed control circuit controls the supply of current to the take-up spool motor. Pulses having a frequency proportional to the camera speed are generated by means of a photo-diode (58) which senses light reflected from reflective segments (57) on the driving shaft (56) of drive sprocket (22), Fig. 2 (not shown). Those pulses are used to generate a signal level also proportional to the actual camera speed, this signal being compared to a reference signal level which is proportional to a selected camera speed. The difference or error between these two signals is used to generate a second series of pulses synchronized with half cycles of the A. C. line frequency, the pulse duration being proportional to this error. These second pulses are used to gate a silicon controlled rectifier circuit which thereby passes current from the A.C. line during a controlled portion of each A. C, cycle. Full manual control is possible by disconnecting the camera signals and controlling the synchronized pulses by means of the adjustable reference signal. The optical compensator consists of a multisided refractive prism (23), Fig. 10 (not shown) rotating on the shaft (56) of sprocket (22) which is parallel to the axle of objective lens 24. A folded system of lenses (62, 64, 67) and prisms (63, 66, 68, 69) passes light from the objective to film (30). The image formed on the film may be viewed for focusing using prism (71) and lens (72) on the reverse side of the film. A centrifugal clutch smooths the transmission of drive from the motor to spool 18.

Title: Arrangement for and method of writing information into magnetic memory elements
IPC: G11C19/06
Filed: 1962-03-27
Abstract: 929,611. Magnetic storage devices. FORD MOTOR CO. Ltd. March 27, 1962 [March 27, 1961], No. 11687/62. Class 38 (2). [Also in Groups XIX and XXXIX] A method of writing information into a magnetic store having first and second flux paths intersecting orthogonally, includes the steps of generating a first flux pulse in the first path and simultaneously generating in the second path, a second flux pulsating a number of times during the first pulse. Element 40, not necessarily of square hysteresis loop material, has apertures 41, 42 threaded by write conductors 43, 45 and output and interrogate conductors 44, 46. Pulse 60 of amplitude I, in conductor 43 shifts the remanent magnetisation only slightly from point 51. The bi-polar pulsating current 61 in conductor 45, of amplitude sufficient to switch the flux around aperture 42, causes the flux around aperture 41 to be switched incrementally to level 52. A strobe pulse 62, of either polarity, in conductor 46, temporarily changes the flux around aperture 42 to produce an output pulse 63 or 64 in conductor 44, depending on the stored information. The output is sensed during interval 65. Read-out is non- destructive. Conductors 43, 44 and 45, 46 may be combined.
